/* ============================================================================
   Email capture box (.capture-box)
   ----------------------------------------------------------------------------
   Used on pages that previously had no way to collect an address at all:
   book pages, the free tools, coaching pages and the paid Q-bank pages.

   Self-contained on purpose. The book pages and some resource pages declare
   their design tokens in an inline <style> block rather than loading
   article.css, so every custom property below carries a literal fallback and
   this file can be dropped onto any page in the site without assuming which
   stylesheet came before it.
